Hi, I'm using GHC head (32bit) on Mac. Recently, building GHC head stops: ---- % make maintainer-clean; perl boot; ./configure --prefix=/ghc-head; make -j3 ranlib: file: .libs/libgmp.a(mp_clz_tab.o) has no symbols ranlib: file: .libs/libgmp.a(obprintf.o) has no symbols ranlib: file: .libs/libgmp.a(obvprintf.o) has no symbols ranlib: file: .libs/libgmp.a(obprntffuns.o) has no symbols ranlib: file: .libs/libgmp.a(repl-vsnprintf.o) has no symbols libtool: link: rm -fr .libs/libgmp.lax libtool: link: ( cd ".libs" && rm -f "libgmp.la" && cp -p "../libgmp.la" "libgmp.la" ) cp libraries/integer-gmp/gmp/gmpbuild/gmp.h libraries/integer-gmp/gmp/ cp libraries/integer-gmp/gmp/gmpbuild/.libs/libgmp.a libraries/integer-gmp/gmp/ inplace/bin/mkdirhier libraries/integer-gmp/gmp/objs cd libraries/integer-gmp/gmp/objs && /usr/bin/ar x ../libgmp.a ranlib libraries/integer-gmp/gmp/libgmp.a ranlib: file: libraries/integer-gmp/gmp/libgmp.a(mp_clz_tab.o) has no symbols ranlib: file: libraries/integer-gmp/gmp/libgmp.a(obprintf.o) has no symbols ranlib: file: libraries/integer-gmp/gmp/libgmp.a(obvprintf.o) has no symbols ranlib: file: libraries/integer-gmp/gmp/libgmp.a(obprntffuns.o) has no symbols ranlib: file: libraries/integer-gmp/gmp/libgmp.a(repl-vsnprintf.o) has no symbols make: *** [all] Error 2 % ---- One more "make -j3" finishes the building. I'm sure that this does not happen before. Are there any guys who get this problem? --Kazu
